Description

Transmission method, device, equipment and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a transmission method, apparatus, device, and storage medium.

Background

In the wireless Radio (NR) technology, a power saving design of a User Equipment (UE) is necessary, mainly because the wireless Radio technology supports a larger bandwidth, a higher throughput, and a more complex service and a more complex processing technology matched with the service.

Currently, during paging performed by the UE, a paging advance indication (Paging early indication, PEI) is used as an indication of whether the PDCCH scheduling the paging message needs to be monitored. The UE detects the PEI before detecting the paging message, if the PEI indicates that the subsequent paging message needs to be received, the UE continues to receive the paging message, otherwise, the UE can enter a low power consumption or dormant state, so that the power consumption of the UE is reduced. Therefore, how to accurately determine the resource location of PEI is important for UE.

As shown in fig. 1, the method may include:

step 101, determining the resource position of PEI according to the target paging frame PF.

In this embodiment, the resource location refers to a time domain location corresponding to PEI, and when PEI is PEI based on a physical downlink control channel (Physical downlink control channel, PDCCH), the time domain location corresponding to PEI is a time domain location corresponding to a first PDCCH listening opportunity of PEI based on PDCCH.

Wherein, the target PF is determined according to the paging parameter.

Wherein the paging parameter includes at least one of:

discontinuous reception DRX cycle T; or (b)

The total number of PFs N in each DRX cycle; or (b)

The total number Ns of paging occasions PO in each PF; or (b)

A radio frame number SFN_PF corresponding to the PF; or (b)

The first parameter A, A represents the total number of PFs to which PEI corresponds.

The target PF is one of A PFs corresponding to the PEI.

Wherein A is an integer of 1 or more.

The radio frame number may also be called a system frame number, and the value range of the radio frame number is 0 to 1023.

In some embodiments, a can be obtained in a variety of ways. As one possible implementation, a system message may be received, where the system message may include a. That is, a is included in the system message broadcast by the base station. As another possible implementation, a is related to Ns and N1, where N1 represents the total number of Paging Occasions (POs) corresponding to PEI, and a may be determined according to N1 and Ns.

In one embodiment of the present disclosure, the above a satisfies: a= (Ceil (N1/Ns)), where Ceil represents an upward rounding.

In some embodiments, in the case where a is an integer greater than 1, the interval of a PFs corresponding to PEI is smaller than the first threshold.

The first threshold represents a critical value of the number of radio frames or paging frames of intervals of a PFs corresponding to the PEI.

Wherein the first threshold is related to T and N.

Wherein the first threshold value may be known in a number of ways. For example, the UE may also receive a system message of the base station, where the system message includes a first threshold. For another example, the UE may obtain the first threshold according to a communication protocol standard, that is, the first threshold may be agreed in the communication protocol standard used by the UE.

In some embodiments, the interval of the a PFs may refer to an interval between the a PFs, or may refer to an interval between a first PF and a last PF corresponding to one PEI.

In one embodiment of the present disclosure, one possible implementation manner of the target PF according to the paging parameter determination is: a first index is determined based on the paging parameters, wherein the first index is used to determine the target PF, the first index is determined based on intermediate values Y and a, the intermediate values Y being related to sfn_pf, N and T.

In some embodiments, the UE may determine a first index corresponding to each PF according to the intermediate values Y and a, and may agree in the communication protocol standard that the PF of the first index takes the value of the first value as the target PF.

Wherein, the value range of the first numerical value is any integer from 0 to A-1. That is, the PF corresponding to any one value of the first index is set to 0, …, a-1 may be defined as the target PF in the communication protocol standard.

In other embodiments, the UE may determine a first index corresponding to each PF according to the intermediate values Y and a, and may also use the PF of the first index with the first value as the target PF by broadcasting a system message. Wherein, the value range of the first numerical value is any integer from 0 to A-1. And broadcasting a system message to inform that the PF corresponding to any one value in the first index is 0, … and A-1 is the target PF.

In some embodiments, the first value may be 0. That is, a PF having a value of 0 of the first index may be contracted as the target PF, that is, the first PF of the a PFs may be contracted as the target PF.

In some embodiments, the first index, Y, and a described above satisfy: first index=y mod a, where mod represents the remainder.

In one embodiment of the present disclosure, the above Y satisfies: y=floor (sfn_pf N/T), where floor denotes a rounding down.

It will be appreciated that in some embodiments, the first Index pf_index satisfies the following formula: pf_index= (floor (sfnpf x N/T)) mod a.

In one embodiment of the present disclosure, one possible implementation manner of determining the resource location of PEI according to the target paging frame PF is: determining a reference frame corresponding to PEI according to a target PF and a first offset value, wherein the first offset value represents an offset value between the target PF and the reference frame, wherein the target PF, the first offset value and the reference frame satisfy the following relation (SFN_PEI+PEI_offset) mod T=SFN_OPF, or SFN_PEI+PEI_offset=SFN_OPF, wherein the SFN_PEI represents a radio frame number of the reference frame, the PEI_offset represents the first offset value, the SFN_OPF represents a radio frame number corresponding to the target PF, and mod represents a margin; the resource location of the PEI is determined from the reference frame.

It is to be understood that the first offset value may be a frame level offset, a slot level offset, or a symbol level offset.

The first offset is preferably a frame level offset. For example, the system message configures the first offset to be 1 radio frame or 2 radio frames.

In one embodiment of the present disclosure, an exemplary implementation of determining the resource location of PEI based on the reference frame is as follows: determining a second index PEI_i_s corresponding to the PEI in the reference frame, wherein PEI_i_s meets the following conditions: pei_i_s= (floor (ue_id/N) mod Ns) mod x, where N1 represents the total number of paging occasions corresponding to PEI; x represents the total number of PEI corresponding to the reference frame, UE_ID represents the identification of the UE, and mod represents the remainder; and determining a target value corresponding to the second index from the X second offset values according to the second index, and determining the resource position of the PEI according to the reference frame and the target value.

In one embodiment of the present disclosure, the above X may be in a variety of ways. For example, a system message sent by a base station is received, wherein the system message includes X. That is, the UE may acquire X from the system message for which the base station is configured. As another example, the X may be determined by the UE based on Ns and N1, in relation to Ns and N1.

In one embodiment of the present disclosure, the above X satisfies: x=ceil (Ns/N1), where Ceil represents an upward rounding.

In one embodiment of the present disclosure, the value of X may be 1,2, or 4. That is, x=1, 2, or 4 as described above.

The second offset may be a frame level offset, a slot level offset, or a symbol level offset, and in this embodiment, the second offset is preferably a symbol level offset.

For example, assuming n=t, ns=4, n1=8, a= (Ceil (N1/Ns))=2, the procedure for the ue to calculate pf_index is shown in table 1 below. At this time, when the sfn_pf corresponding to the PF where the PO monitored by the UE is equal to 2M, M is an integer greater than or equal to 0, the UE determines, according to the calculation formula of pf_index, that pf_index=0, and the UE may determine that the target PF is the PF where the PO monitored by the UE itself is located, and determine the reference frame according to the target PF. When the sfn_pf corresponding to the PF where the PO monitored by the UE is equal to 2m+1, M is an integer greater than or equal to 0, the UE may bring sfn_pf=2m into the calculation formula of pf_index to obtain pf_index=0 according to the calculation formula of pf_index, and determine the PF corresponding to sfn_pf=2m as the target PF, that is, the UE determines that the target PF is the previous PF of the PF where the PO monitored by the UE is located, and determines the reference frame according to the target PF. As shown in fig. 2, in this figure, the PF corresponding to sfn_pf=2m is the target PF, as indicated by a symbol C in fig. 2. In fig. 2, the relationship among the reference frame, the first offset value, the second offset value, and the target PF is also illustrated.

TABLE 1

For another example, assuming n=t, ns=4, n1=4, or 2 or 1, a= (Ceil (N1/Ns))=1, the procedure for the ue to calculate pf_index is shown in table 2 below. At this time, whether the sfn_pf corresponding to the PF where the PO monitored by the UE is equal to 2M or 2m+1, M is an integer greater than or equal to 0, the pf_index determined by the UE according to the calculation formula of the pf_index is equal to 0, the UE may determine that the target PF is the PF where the PO monitored by the UE itself is located, and determine the reference frame according to the target PF. As shown in fig. 3, n1=4, sfn_pf=2m, and sfn_pf=2m+1 are target PFs, as indicated by a symbol D in fig. 3. As shown in fig. 4, n1=2, sfn_pf=2m, and sfn_pf=2m+1 are both target PFs, as indicated by a symbol E in fig. 4. As shown in fig. 5, n1=1, sfn_pf=2m, and sfn_pf=2m+1 are both target PFs, as indicated by a symbol F in fig. 5. It should be noted that the second bias value may be one of the second bias value 0, the second bias value 1, the second bias value 2, and the third bias value 3 in fig. 5. Wherein the first offset value 0 represents an offset value between a start position of the reference frame and a first PEI of the corresponding plurality of PEIs in the reference frame, the second offset value 1 represents an offset value between a start position of the reference frame and a second PEI of the corresponding plurality of PEIs in the reference frame, the second offset value 2 represents an offset value between a start position of the reference frame and a third PEI of the corresponding plurality of PEIs in the reference frame, and the second offset value 3 represents an offset value between a start position of the reference frame and a fourth PEI of the corresponding plurality of PEIs in the reference frame.

TABLE 2

In summary, the UE determines that the PF where the PO monitored by itself is the target PF, or the UE determines that the PF of the first pf_index=0 before the PF where the PO monitored by itself is the target PF. Here, the PF of the first pf_index=0 refers to the PF of which the PF having the smallest distance from the PF where the PO monitored by the UE is located, and the PF of the first pf_index=0 is located before the PF where the PO monitored by the UE is located from the time point of view. After determining the target PF, the UE determines a reference frame according to the target PF.

It should be noted that, the UE determines that the monitored PO and the PF where the UE is located satisfy the following relationship:

(SFN+PF_offset)mod T＝(T div N)*(UE_ID mod N)

wherein the ue_id represents the identity of the UE, and as an example, the UE id=5g-S-TMSI mod 1024, where the 5G-S-TMSI is a 48-bit string.

It should be noted that, each paging frame includes Ns POs, and an index of each PO is i_s, which is determined according to the following formula:

i_s＝floor(UE_ID/N)mod Ns

among them, it should be noted that an exemplary procedure for determining a DRX cycle finally used for receiving paging by the UE is: and the UE determines a DRX period finally used for receiving paging according to the minimum value of the DRX and the default DRX period configured by the high-layer signaling and/or the core network signaling.

Wherein higher layer signaling may include, but is not limited to, radio resource control RRC (Radio Resource control) signaling.

Wherein the default DRX cycle may be derived from system information, that is, the system information includes the default DRX cycle.

In addition, it should be noted that, for the UE, the UE listens to one PO (Paging occasion) every DRX cycle. One PO is a set of PDCCH monitoring opportunities (MO, monitoring occasion) and may contain a number of slots (e.g., subframes or OFDM symbols) on which paging DCI is transmitted. A Paging Frame (Paging Frame) is a radio Frame that may contain one or more POs or starting points of POs. In an exemplary embodiment of the present disclosure, after determining the reference frame corresponding to the PEI, the UE needs to determine a specific time domain position of the PEI according to a start point of the reference frame, where the specific time domain position of the PEI may be determined by a second offset value, and the base station may configure the second offset by using a second parameter in a system message, specifically, the second parameter may include at least one second offset, that is, the second parameter includes at least one value, where each value corresponds to one second offset value, and the second parameter may be represented as a first PDCCH monitoring opportunity, first PDCCH-monitoring time O. When 1 PEI corresponds to the reference frame, 1 numerical value can be configured in the first PDCCH-MonitoringOccasionofPEI-O; when 2 PEI's are corresponding in the reference frame, 2 values can be configured in the first PDCCH-MonitoringOccasionofPEI-O; when 4 PEI's are corresponding in the reference frame, 4 values can be configured in the first PDCCH-MonitoringOccionofPEI-O. When the reference frame corresponds to a plurality of PEI, the UE needs to determine which value of a plurality of values in the first PDCCH-MonitoringOccionofPEI-O corresponds to the PEI monitored by the UE, and at this time, the UE can determine a target value according to the second index, wherein the target value is a value corresponding to a second offset value corresponding to the PEI monitored by the UE in the X values.

It is understood that the second index determines a target index of PEI in at least 1 PEI indexes included in the reference frame, where the target index may be used to determine a specific resource location of PEI in the reference frame. For example, if the reference frame includes 2 PEI, the base station configuration "first pdcch-motoringoccidioofpei-O" includes two values, the resource position of PEI corresponding to pei_i_s=0 in the reference frame is determined according to the first value in "first pdcch-motoringoccidioofpei-O", and the resource position of PEI corresponding to pei_i_s=1 in the reference frame is determined according to the second value in "first pdcch-motoringoccidioofpei-O".

The specific process of determining the resource location of the PEI according to the second index in the case of reference frame determination is described in more detail below:

the UE determines the PDCCH listening opportunity of PEI based on the first PDCCH listening opportunity "first PDCCH-MonitorOccionofPEI-O" of the paging search space and downlink configuration common system message block (System Information Block, SIB) "DownlinkConfigCommonSIB" field configuration and the paging PDCCH listening opportunity paging PDCCH MO total number "nrofPDCCCHMonitingOccionPerSSB-InPO" corresponding to one synchronization signal block (Synchronization Signal Block, SSB). When the paging search space configuration "searchspace=0", the PDCCH listening opportunity of PEI is the same as the remaining minimum system information (Remaining Minimum SI, RMSI).

When "searchspace id" of the paging search space configuration is not equal to 0, the UE listens to the (pei_i_s+1) th PEI. PEI is a set of "s×1" consecutive PDCCH listening opportunities, where S is the number of SSBs actually transmitted determined according to the SSB location information carried by SIB1, and X1 represents the total number of paging PDCCH MO corresponding to each SSB configured by "nrofpdccs hmonitingoccosion perssb-InPO", and if the value is not configured, X1 is equal to 1. When the "first PDCCH-monitoringOcciofPEI-O" is configured, the first PDCCH listening occasion of the (PEI_i_s+1) th PEI is the (PEI_i_s+1) th value of the second parameter "first PDCCH-monitoringOcciofPEI-O" configured at a higher layer, otherwise, the first PDCCH listening occasion of the (PEI_i_s+1) th PEI is equal to PEI_i_s X1.

Step 102, receiving PEI at the resource location, wherein PEI is used to indicate the existence of paging.

In one embodiment of the present disclosure, the PEI described above may be used to indicate at least one of the following, including: whether Paging downlink control information (Downlink Control Information) exists at the PO, whether Paging DCI is detected at the PO, whether Paging information is detected, or whether wake-up is needed to detect the Paging information in the Paging period; either a paging message exists at the PO, or paging DCI is detected at the PO, or a paging message is detected, or a wake-up is required to detect a paging message during the paging cycle.

In some embodiments of the present disclosure, the PEI may indicate the presence of a paging message on at least one paging occasion to which the PEI corresponds.

Specifically, the UE may determine the paging occasion to which it needs to monitor, determine, according to PEI, the existence of a paging message on the paging occasion, and determine, according to the existence of a paging message on the paging occasion, whether to enter a low power consumption or sleep state.

According to the transmission method, the target PF is determined from the PF corresponding to the PEI accurately by combining the paging parameter, the resource position of the PEI is determined accurately based on the target PF, and the PEI is received at the resource position. Therefore, the UE can determine whether to enter a low power consumption or sleep state according to the instruction of the PEI, so that the UE can be prevented from continuously monitoring the paging control information on the PO, and the power consumption of the UE is reduced.

Fig. 6 is a flowchart illustrating another transmission method according to an embodiment of the present disclosure, which is performed by a UE.

As shown in fig. 6, the method may include:

step 601, determining the resource location of PEI according to the time window of PEI.

The resource location of PEI in this embodiment refers to the resource location of PEI that the UE needs to monitor.

In some embodiments, one possible implementation of determining the resource location of the PEI according to the time window of the PEI may be: the starting resource position of the PEI monitored by the UE can be determined according to the starting position of the time window of the PEI, and the resource position of the PEI monitored by the UE is positioned in the time window of the PEI.

At step 602, PEI is received at a resource location, wherein PEI is used to indicate the presence of a page.

According to the transmission method of the paging advance indication, the resource position of the PEI is determined by combining the time window of the PEI, and the PEI is received at the resource position. Therefore, the UE can determine whether to enter a low power consumption or sleep state according to the instruction of the PEI, so that the UE can be prevented from continuously monitoring the paging control information on the PO, and the power consumption of the UE is reduced.

Fig. 7 is a flowchart illustrating another transmission method according to an embodiment of the present disclosure, which is performed by a UE.

As shown in fig. 7, the method may include:

in step 701, the resource location of PEI is determined according to the time windows of the target paging frames PF and PEI.

In one embodiment of the present disclosure, the time window of the PEI is determined by a start position (ptw_start_pei) of the time window of the PEI and an end position (ptw_end_pei) of the time window of the PEI.

In some embodiments, the time window of the PEI may include: at least one DRX cycle.

For each DRX cycle, a target PF in the DRX cycle may be determined, and the resource location of the PEI may be determined based on the target PF.

Wherein the target PF is determined according to the paging parameters.

For a specific implementation manner of determining the target PF according to the paging parameter, reference may be made to the related description of the foregoing embodiment, which is not repeated herein.

Wherein the paging parameters include at least one of:

discontinuous reception DRX cycle T; or (b)

The total number of PFs N in each DRX cycle; or (b)

The total number Ns of paging occasions PO in each PF; or (b)

A radio frame number SFN_PF corresponding to the PF; or (b)

The target PF is one of A PFs corresponding to the PEI.

Wherein A is an integer greater than or equal to.

In some embodiments, a can be obtained in a variety of ways. As one possible implementation, a system message may be received, where the system message may include a. That is, a is included in the system message broadcast by the base station. As another possible implementation, a is related to Ns and N1, N1 represents the total number of paging occasions corresponding to PEI, and a may be determined according to N1 and Ns.

Wherein the first threshold is related to T and N.

For a specific implementation manner of determining the resource location of the PEI according to the target PF, reference may be made to the description of the foregoing embodiment, which is not repeated herein.

Based on the above description, it can be seen that, in the technical solution of determining the resource location of PEI by combining the time window of the target paging frame PF and the time window of PEI, after determining the time window of PEI, the resource location of PEI in the time window of PEI may be determined by the method shown in the embodiment of fig. 1.

At step 702, PEI is received at a resource location, wherein PEI is used to indicate the presence of a page.

For a specific implementation of step 702, reference may be made to the description of the above embodiment, which is not repeated here.

According to the transmission method of the embodiment of the disclosure, the resource position of PEI is determined according to the time window of the target paging frame PF and PEI, and PEI is received at the resource position. Therefore, the UE can determine whether to enter a low power consumption or sleep state according to the instruction of the PEI, so that the UE can be prevented from continuously monitoring the paging control information on the PO, and the power consumption of the UE is reduced.

For the time window of PEI in any of the foregoing embodiments, one possible implementation manner of determining the time window of PEI, as shown in fig. 8, may include:

step 801, determining a time window of PEI according to the third offset value, the start position and the end position of the paging time window PTW corresponding to the UE.

Wherein the third offset value represents an offset value between a starting position of the time window of the PEI and a starting position of the PTW.

The paging time window PTW corresponding to the UE may be determined by the prior art. An exemplary embodiment of determining the paging time window PTW corresponding to the UE may be: and determining a paging time window PTW corresponding to the UE according to the identification information of the UE and the extended discontinuous reception eDRX period corresponding to the UE.

It should be noted that the PTW window is UE-level, and the PTW windows of different UEs may be different. The PTW window is determined based on the PH, the start position of PTW within PH (PTW_start) and the end position of PTW (PTW_end).

Wherein, the superframe number (H-SFN) where PH is located satisfies the following relationship:

H-SFN mod TeDRX_CN＝(UE_ID_H mod TeDRX_CN)

wherein, teDRX_CN is the length of eDRX period, which takes super frame as unit, 1 super frame is equal to 1024 wireless frames; ue_id_h is an ID corresponding to UE, mod represents the remainder.

The radio frame number SFN where the start position (ptw_start) of the PTW window is located satisfies the following formula:

sfn=128×iedrx_cn, where

ieDRX_CN＝floor(UE_ID_H/TeDRX_CN)mod 8

The radio frame number SFN where the end position (ptw_end) of the PTW window is located satisfies the following formula:

sfn= (ptw_start+l 100-1) mod 1024, where L is the configured PTW window length.

In one embodiment of the present disclosure, according to the third offset value, the starting position and the ending position of the paging time window PTW corresponding to the UE, one possible implementation manner of determining the time window of PEI is: and determining the starting position PTW_start_PEI of the time window of PEI according to the starting position of PTW and the third offset value.

In one embodiment of the present disclosure, the end position of the time window of the PEI is determined according to the end position of the PTW, which may be taken as the end position of the time window of the PEI, as an example.

In another embodiment of the present disclosure, one possible implementation manner of determining the time window of PEI according to the third offset value, the start position and the end position of the paging time window PTW corresponding to the UE is: and determining the end position PTW_end_PEI of the time window of PEI according to the end position of the PTW and the third offset value.

In one embodiment of the present disclosure, the starting position of the time window of the PEI may be determined from the starting position of the PTW.

In another embodiment of the present disclosure, one possible implementation of the time window of PEI is determined according to the third offset value, the start position and the end position of the paging time window PTW corresponding to the UE: determining a starting position PTW_start_PEI of a time window of PEI according to the starting position of the PTW and the third bias value; and determining the end position PTW_end_PEI of the time window of PEI according to the end position of the PTW and the third offset value.

In one embodiment of the present disclosure, ptw_start_pei satisfies: ptw_start_pei=ptw_start-pei_offset 3, or, (ptw_start_pei+pei_offset 3) mod a first preset value=ptw_start, where ptw_start represents the start position of PTW, pei_offset3 represents the third offset value, mod represents the remainder.

In an embodiment of the present disclosure, the first preset value may be 1024.

In one embodiment of the present disclosure, ptw_end_pei satisfies: ptw_end_pei=ptw_end-pei_offset 3, or (ptw_end_pei+pei_offset 3) mod a second preset value=ptw_end, where ptw_end represents the end position of the PTW, pei_offset3 represents the third offset value, mod represents the remainder.

In an embodiment of the present disclosure, the second preset value may be 1024.

In one embodiment of the present disclosure, in a case where a radio frame number corresponding to a start position of the PTW is greater than or equal to a third offset value, the ptw_start_pei satisfies: ptw_start_pei=ptw_start-pei_offset 3; ptw_end_pei satisfies: ptw_end_pei=ptw_end-pei_offset 3.

For example, if the UE is in an idle state in the case where the eDRX cycle is configured, the UE listens to the paging occasion PO within the PTW window in the eDRX cycle, assuming that the UE determines that its corresponding superframe number (Hyperframe-System Frame number, H-SFN) =2 in the eDRX cycle, and the UE listens to the PO within the PTW window in H-sfn=2, and the PO outside the PTW window does not. In addition, assuming that one PEI corresponds to 2 POs in the PTW window, as shown in fig. 9, the relationship between the PTW corresponding to the UE and the time window corresponding to the PEI is shown in an example diagram, it can be seen from fig. 9 that the start position ptw_start_pei of the time window of the PEI is located before the start position ptw_start of the PTW, and a third offset value is spaced between the start position ptw_start_pei of the time window of the PEI and the start position ptw_start of the PTW, and ptw_end_pei is located before the ptw_end, and a third offset value is spaced between the ptw_end and the ptw_pei.

In another embodiment of the present disclosure, in a case where the radio frame number corresponding to the end position of the PTW is smaller than the third offset value, the ptw_start_pei satisfies: (ptw_start_pei+pei_offset 3) mod first preset value=ptw_start; ptw_end_pei satisfies: (ptw_end_pei+pei_offset 3) mod second preset value=ptw_end.

In an embodiment of the present disclosure, in a technical solution for determining a resource location of PEI by combining a time window of a target paging frame PF and PEI, a value of a third offset value in the technical solution is the same as a value of a first offset value, where the first offset value represents an offset value between reference frames corresponding to the target PF and PEI.

In one embodiment of the present disclosure, the superframe number corresponding to PEI is the same as the superframe number corresponding to PF, or the superframe number corresponding to PEI is equal to the superframe number corresponding to PF minus a third preset value.

In one embodiment of the present disclosure, the third preset value is 1 or 1024. That is, ph_pei and PH satisfy the following formula: ph_pei=ph-1, or ph_pei=ph-1024, where ph_pei represents the superframe number corresponding to PEI and PH represents the superframe number corresponding to PF.

In one embodiment of the present disclosure, in a case where the radio frame number corresponding to the start position of the PTW is greater than or equal to the third offset value, h_pei=ph, where ph_pei represents the superframe number corresponding to PEI and PH represents the superframe number corresponding to PF.

In another embodiment of the present disclosure, in a case where the radio frame number corresponding to the start position of the PTW is smaller than the third offset value, ph_pei and PH satisfy the following formula: ph_pei=ph-1, or ph_pei=ph-1024, where ph_pei represents the superframe number corresponding to PEI and PH represents the superframe number corresponding to PF.

For the time window of PEI in any of the foregoing embodiments, another possible implementation manner of determining the time window of PEI is: and determining a time window of the PEI according to at least one of the third bias value, the starting position of the PTW and the ending position of the PTW.

In one embodiment of the present disclosure, the third offset value is the same as the first offset value, where the first offset value represents an offset value between reference frames corresponding to the target PF and PEI.

In one embodiment of the present disclosure, the target PF, the first offset value, and the reference frame satisfy the following relationship (sfn_pei+pei_offset) mod t=sfn_opf, or sfn_pei+pei_offset=sfn_opf, where sfn_pei represents a radio frame number of the reference frame, pei_offset represents the first offset value, sfn_opf represents a radio frame number corresponding to the target PF, and mod represents the remainder.

It should be noted that, for a UE in a non-connected state (the non-connected state includes an IDLE state (IDLE) or an INACTIVE state (INACTIVE)), if the eDRX period of the UE exceeds 1024 radio frames, the time window of PEI may be determined according to the method for determining the time window of PEI shown in fig. 8.

Fig. 10 is a flowchart of a transmission method according to an embodiment of the present disclosure. The transmission method is performed by a base station. Wherein a base station is an entity on the network side for transmitting or receiving signals. The base station may comprise a plurality of cells serving the terminal. A base station may also be called an access point or may be a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or other names, depending on the particular application. The network device may be operable to exchange received air frames with internet protocol (Internet Protocol, IP) packets as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communication network. The network device may also coordinate attribute management for the air interface. For example, the network device according to the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in a global system for mobile communications (Global System for Mobile communications, GSM) or code division multiple access (Code Division Multiple Access, CDMA), a network device (NodeB) in a wideband code division multiple access (Wide-band Code Division Multiple Access, WCDMA), an evolved network device (evolutional Node B, eNB or e-NodeB) in a long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in a 5G network architecture (next generation system), a home evolved base station (Home evolved Node B, heNB), a relay node (relay node), a home base station (femto), a pico base station (pico), and the like. In some network structures, the network device may include a Centralized Unit (CU) node and a Distributed Unit (DU) node, which may also be geographically separated.

As shown in fig. 10, the transmission method may include:

in step 1001, the resource location of PEI is determined according to the target paging frame PF.

In this embodiment, the resource location refers to a time domain location corresponding to PEI monitored by a User Equipment (UE) in communication with a base station. When the PEI is the PEI based on the PDCCH, the time domain position corresponding to the PEI is the time domain position corresponding to the first PDCCH monitoring time of the PEI based on the PDCCH.

Wherein the target PF is determined according to the paging parameters.

Wherein, the paging parameter may include at least one of:

discontinuous reception DRX cycle T; or (b)

The total number of PFs N in each DRX cycle; or (b)

The total number Ns of paging occasions PO in each PF; or (b)

A radio frame number SFN_PF corresponding to the PF; or (b)

The target PF is one of A PFs corresponding to the PEI.

Wherein A is an integer of 1 or more.

In some embodiments, a can be obtained in a variety of ways. As one possible implementation, a may be obtained from a system message configured for the UE. As another possible implementation, a is related to Ns and N1, N1 represents the total number of paging occasions corresponding to PEI, and a may be determined according to N1 and Ns.

Wherein the first threshold is related to T and N.

Wherein the first threshold value may be known in a number of ways. For example, the first threshold may be obtained from a system message configured for the UE. That is, the first threshold is included in the system message configured by the base station for the UE. For another example, the first threshold may be obtained according to a communication protocol standard.

In one embodiment of the present disclosure, the above X may be in a variety of ways. For example, X is included in a system message configured for the UE. For another example, the X may be determined based on Ns and N1, where X is related to Ns and N1.

In an exemplary embodiment of the present disclosure, after determining the reference frame corresponding to the PEI, the base station needs to determine a specific time domain position of the PEI according to the start point of the reference frame, where the specific time domain position of the PEI may be determined by using the second offset value. The base station may configure the second offset through a second parameter in the system message, specifically, the second parameter may include at least one second offset, that is, the second parameter includes at least one value, where each value corresponds to one second offset value, and the second parameter may be represented as a first PDCCH-monitoring opportunity pei-O. When 1 PEI corresponds to the reference frame, 1 numerical value can be configured in the first PDCCH-MonitoringOccasionofPEI-O; when 2 PEI's are corresponding in the reference frame, 2 values can be configured in the first PDCCH-MonitoringOccasionofPEI-O; when 4 PEI's are corresponding in the reference frame, 4 values can be configured in the first PDCCH-MonitoringOccionofPEI-O. When the reference frame corresponds to a plurality of PEI, the base station needs to determine which value of a plurality of values in the first PDCCH-MonitoringOccionofPEI-O corresponds to the PEI required to be monitored by the UE, and at this time, the base station can determine a target value according to the second index, where the target value is a value corresponding to a second offset value corresponding to the PEI monitored by the UE in the X values.

It is understood that the second index determines a target index of PEI in at least 1 PEI indexes included in the reference frame, where the target index may be used to determine a specific resource location of PEI in the reference frame. For example, the reference frame includes 2 PEI, and the "first pdcch-monitoringOccasionofPEI-O" configured by the base station for the UE includes two values, where the resource position of the PEI corresponding to PEI_i_s=0 in the reference frame is determined according to the first value in the "first pdcch-monitoringOccasionofPEI-O", and the resource position of the PEI corresponding to PEI_i_s=1 in the reference frame is determined according to the second value in the "first pdcch-monitoringOccasiofPEI-O".

the base station determines the PDCCH listening opportunity of PEI based on the first PDCCH listening opportunity "first PDCCH-MonitorOccionofPEI-O" of the paging search space and downlink configuration common system message block (System Information Block, SIB) "DownlinkConfigCommonSIB" field configuration and the paging PDCCH listening opportunity paging PDCCH MO total number "nrofPDCCCHMoningtorongOccionPerSSB-InPO" corresponding to one synchronization signal block (Synchronization Signal Block, SSB). When the paging search space configuration "searchspace=0", the PDCCH listening opportunity of PEI is the same as the remaining minimum system information (Remaining Minimum SI, RMSI).

When "searchspace id" of the paging search space configuration is not equal to 0, the base station monitors the (pei_i_s+1) th PEI if it is determined that the UE needs to monitor. PEI is a set of "s×1" consecutive PDCCH listening opportunities, where S is the number of SSBs actually transmitted determined according to the SSB location information carried by SIB1, and X1 represents the total number of paging PDCCH MO corresponding to each SSB configured by "nrofpdccs hmonitingoccosion perssb-InPO", and if the value is not configured, X1 is equal to 1. When the "first PDCCH-monitoringOcciofPEI-O" is configured, the first PDCCH listening occasion of the (PEI_i_s+1) th PEI is the (PEI_i_s+1) th value of the second parameter "first PDCCH-monitoringOcciofPEI-O" configured at a higher layer, otherwise, the first PDCCH listening occasion of the (PEI_i_s+1) th PEI is equal to PEI_i_s X1.

Step 1002, sending PEI at the resource location, where the PEI is used to indicate the presence of paging.

The resource positions of the PEI determined by the base station and the UE are consistent. Correspondingly, the base station transmits PEI at the resource location corresponding to PEI. The UE receives PEI at the resource position, determines the existence of paging messages on paging occasions PO to be monitored by the PEI according to the PEI, and determines whether to enter a low power consumption or sleep state according to the existence of the paging messages on the paging occasions.

According to the transmission method, the target PF is determined accurately from the PFs corresponding to the PEI by combining the paging parameters, the resource position of the PEI is determined accurately based on the target PF, and the PEI is sent on the resource position. Therefore, the base station can accurately determine the resource position of PEI and accurately transmit PEI based on the resource position.

Fig. 11 is a flowchart illustrating another transmission method according to an embodiment of the present disclosure, which is performed by a base station.

As shown in fig. 11, the method may include:

step 1101, determining the resource location of the PEI according to the time window of the PEI.

The resource location of PEI in this embodiment refers to the resource location of PEI that needs to be monitored by the UE that communicates with the base station.

In step 1102, PEI is received at a resource location, wherein PEI is used to indicate the presence of a page.

For a specific implementation of step 1102, reference may be made to the related description of the above embodiment, which is not repeated here.

According to the transmission method of the paging advance indication, the resource position of the PEI is accurately determined by combining the time window of the PEI, and the PEI is sent at the resource position. Therefore, the base station can accurately determine the resource position of PEI and accurately transmit PEI based on the resource position.

Fig. 12 is a flowchart of a transmission method according to an embodiment of the present disclosure, where the transmission method is performed by a base station.

As shown in fig. 12, the method may include:

step 1201, determining the resource location of PEI according to the time window of the target paging frame PF and PEI.

For each DRX cycle, the resource location of the PEI may be determined based on the target PF in the DRX cycle and based on the target PF.

Wherein the target PF is determined according to the paging parameters.

Wherein, the paging parameter may include at least one of:

discontinuous reception DRX cycle T; or (b)

The total number of PFs N in each DRX cycle; or (b)

The total number Ns of paging occasions PO in each PF; or (b)

A radio frame number SFN_PF corresponding to the PF; or (b)

The target PF is one of A PFs corresponding to the PEI.

Wherein A is an integer greater than or equal to.

The UE refers to a UE that communicates with the base station.

Wherein the first threshold is related to T and N.

Wherein the first threshold value may be known in a number of ways. For example, the first threshold may be obtained from a system message configured for the UE. That is, the first threshold is included in a system message configured for the UE. For another example, the first threshold may be obtained according to a communication protocol standard.

Based on the above description, it can be seen that, in the technical solution of determining the resource location of PEI by combining the time window of the target paging frame PF and the time window of PEI, after determining the time window of PEI, the resource location of PEI in the time window of PEI may be determined by the method shown in the embodiment of fig. 10.

Step 1202, receiving PEI at a resource location, wherein PEI is used to indicate the presence of a page.

For a specific implementation of step 1202, reference may be made to the related description of the above embodiment, which is not repeated here.

According to the transmission method of the embodiment of the disclosure, the resource position of PEI is determined according to the time window of the target paging frame PF and PEI, and PEI is sent at the resource position. Therefore, the base station can accurately determine the resource position of the PEI monitored by the UE and send the PEI on the resource position.

For the time window of PEI in any of the foregoing embodiments, one possible implementation manner of determining the time window of PEI, as shown in fig. 13, may include:

in step 1301, a time window of PEI is determined according to the third offset value, and a start position and an end position of a paging time window PTW corresponding to a user equipment UE in communication with the base station.

The paging time window PTW corresponding to the UE may be determined by the prior art. One exemplary embodiment for determining the paging time window PTW corresponding to the UE may be: and determining a paging time window PTW corresponding to the UE according to the identification information of the UE and the extended discontinuous reception eDRX period corresponding to the UE.

H-SFN mod TeDRX_CN＝(UE_ID_H mod TeDRX_CN)

sfn=128×iedrx_cn, where

ieDRX_CN＝floor(UE_ID_H/TeDRX_CN)mod 8

sfn= (ptw_start+l 100-1) mod 1024, where L is the configured PTW window length.

In one embodiment of the present disclosure, the end position of the time window of the PEI is determined from the end position of the PTW. As an example, the end position of the PTW may be taken as the end position of the time window of the PEI.

In one embodiment of the present disclosure, the first preset value is 1024.

In one embodiment of the present disclosure, the second preset value is 1024.

In one embodiment of the present disclosure, in a case where a system frame number corresponding to a start position of the PTW is greater than or equal to a third offset value, the ptw_start_pei satisfies: ptw_start_pei=ptw_start-pei_offset 3; ptw_end_pei satisfies: ptw_end_pei=ptw_end-pei_offset 3.

In another embodiment of the present disclosure, in a case where the system frame number corresponding to the end position of the PTW is smaller than the third offset value, the ptw_start_pei satisfies: (ptw_start_pei+pei_offset 3) mod first preset value=ptw_start; ptw_end_pei satisfies: (ptw_end_pei+pei_offset 3) mod second preset value=ptw_end.

In one embodiment of the present disclosure, in a case where the system frame number corresponding to the start position of the PTW is greater than or equal to the third offset value, h_pei=ph, where ph_pei represents the superframe number corresponding to PEI and PH represents the superframe number corresponding to PF.

In another embodiment of the present disclosure, in the case that the system frame number corresponding to the start position of the PTW is smaller than the third offset value, ph_pei and PH satisfy the following formula: ph_pei=ph-1, or ph_pei=ph-1024, where ph_pei represents the superframe number corresponding to PEI and PH represents the superframe number corresponding to PF.
